For a given material Young's modulus is 200 GN/m2 and modulus of rigidity is 80 GN/m2. The value of Poisson's ratio is
0.15
0.20
0.25
0.30
0.40

29.
The ratio of the moment of inertia of a circular plate and that of a square plate for equal depth, is
less than one
equal to one
more than one
equal to 3π/16
none of these.
Answer: Option
Explanation:

For circular plate, MI = π*d^4/64.

For square plate, MI = d^4/12.

So, Ratio = MI of circular plate/MI of square plate.

= 3*π/16.
